Obama has stepped into the debate after the unarmed African-American 17 year old was shot dead in a Florida gated community on February 26 by a neighborhood watch volunteer, George Zimmerman, who has not been arrested and who claims he was acting in self-defense.

The president admitted on Friday he had been moved by the racially-charged incident, insisting, "If I had a son, he'd look like Trayvon," and calling for an official probe.

Now a slew of stars have backed Obama, with director Lee taking to Twitter.com to post a photo of his own son wearing a hooded sweatshirt as a sign of solidarity for Martin, who was wearing a 'hoodie' when he was gunned down.

Lee quoted Obama before tweeting, "My 14 Year Old Son, Jackson Lewis Lee. HE IS TRAYVON MARTIN," while Sex And The City star Gilles Marini also released a photo of himself in a hoodie, adding, "I loved what Obama said... Here (is) my hoodie pic as respect to Trayvon."

Rapper Combs showed fans a picture of himself wearing a hoodie while holding a photo of Martin, alongside the caption, "I didn't know wearing a hoodie made me a target. Justice Is Needed."

Ferrell also offered to donate money to the newly-launched Trayvon Martin Foundation, which fights racism, for every person who re-tweets the message, "R.I.P Trayvon Martin", and actress Holly Robinson Peete added, "Wow I never thought I'd see the day a US President would say 'If I had a son he'd look like Trayvon Martin'. Justice 4 (for) Trayvon."
